Hot on the heels of Apple's 8.4 million iPhones sold in Q3, AT&T announces a record-breaking 3.2 million of those were activated on their network. Their churn levels were lower than ever as well, 1.01 percent postpaid churn and 1.29 percent total churn, and the all-important ARPU (average monthly revenues per subscriber) up 3.4 percent.

On June 24, AT&T began offering iPhone 4, the most powerful iPhone yet. Preorder sales of iPhone 4 were 10 times higher than the first day of preordering for iPhone 3GS a year earlier. For the full second quarter, AT&T iPhone activations totaled 3.2 million, the most quarterly iPhone activations ever. Approximately 27 percent of those activations were for customers who were new to AT&T.

27 percent new to AT&T, going into the 4th year of exclusivity? Yeah, that's probably why they stick with that "I hate you, don't leave me" borderline relationship with Apple.

And all this with iPhone 4 demand still exceeding Apple's supply, and the white iPhone 4 still waiting on a limited, late July launch.
